In this article, an electronic differential control algorithm suitable for distributed drive electric vehicles is proposed. Considering the vertical forces transfer of both sides wheels and vehicle stability during the vehicle steering process, under the condition of the constant road adhesion coefficient, two driving torque distribution methods are used. The first distribution method that considers the vertical forces transfer of both sides wheels, the second distribution method that add a yaw moment for the vehicle stability during the steering process, in order to acquire the best result of electronic differential, this article compares the effects of the two distribution methods in different speed ranges. Simulations show that in the low-speed stage, the first distribution method can avoid the wheels slipping effectively. In the high-speed stage, the second distribution method can better ensure the vehicle stability. Therefore, the electronic differential control algorithm proposed integrates the advantages of two methods, which in the low-speed range using the first method and in the high-speed range using the second method.
